Specification of Letters Patent.

Application led May 20, '1912. VVSerial No. 698,462.

Patented Feb. 25, 1913.

To all whom t may concern.'

Be it known that I, CHARLES D. WILSON,

a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Firearm; and I do hereby declare the following to be a full, clear, and exact descriptionof the invention, ysuch as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of 'reference marked thereon, which form a part of this specification.

My invention relates particularly to shotguns or the like of the double-barrel type, but is not restrictedto such use, as it may be used in any connection for which it may be adapted or appropriate.

rllhe primary object of my invention is the provision, in a gun of this class, of a lock mechanism, which is simple and inexpensive in its construction, composed of compara tively few parts, and is capable of having its parts easily and quickly assembled, thus enhancing the practicability and commercial value of such guns.

Further objects of the invention are the provision of a lock mechanism, which is carried substantially asfa unit by the trigger/ plate, and adapted to be removed therewith from the gun; the provision of simple and improved safe means for such mechanism, and the provision of improved means which is` operable to lock the stock and barrels in closed o-r firing position and also to release such parts to permit a relative movement thereof to open position. y

Further objects and advantages will be apparent from the following detailed description.

The invention is fully described in the following specification, and While, in its broader aspect, it iscapable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,-

Figure 1 is a sideelevation of a portion of a gun embodying the invention, with the barrel and stock in open position, and with parts broken away. Fig. 2 is a top plan View` of the trigger-plate and lock mechamsm carried thereby, with the parts in cocked position. Fig. 3 is a view similar to Fig. 1, withparts in central longitudinal section, and with the triggers removed. Fig. 4 is a cross-section on the line :v in Fig. ,3,

with the barrels removed. Fig. 5 is a crosssection on the line y, y in Fig. 3. Figs. 6 and 7 are details of parts associated with the forearm hinge. Fig. 8 is a view similar to Fig.V 3 with the barrels and stock in closed position and the lock mechanism iun fired position. 'Fig 9 is a side elevation of the trigger-plate and parts carried thereby, with such parts in fired position, and Fig. 10 is an inner side view of one of the hammers.

Referring to the drawings, 1 designates the customary gun frame, which has the stock attaching arm 2 extending rearwardly from its upper portion, and the water-table arm 3 extending forwardly from its lower portion and hingedly connected to the barrels 5. The trigger-plate 6, which is attached to the under side of the frame is preferably fitted up into a bottom recess of such frame and its arm 3,y and is retained therein by having its forward end in hooked "engagement with the forward end wall of the recess, as at 7, and its rear portion attached to the frame by screws 8 and 9, the latter of which is projected through an opening in the stock part 10 and threaded into the arm 2 of the frame, as shown in Figs. 1 and 3.

Rising, in the present instance, from substantially the Vcentral portion of the triggerplate is a block 11, which is rigidly attached thereto in any suitable manner and has both ends preferably forked to provide the vertical recesses 12 and 13 in the 'opposite ends thereof, with the forward recess 12 extendin the eater distance into the block. The si es o the block 11 are equidistantly spaced from the side edges of the triggerplate, and hammers 14, 14 are carried by pivot-studs 14 projecting therefrom, as best shown in Fig. 5, the outer sides of the hammers being preferably flush with the plate edges. Each hammer has its firing movements infiuenced by a coiled expansion spring 15, which encircles a rod .16 and a stud 19 rising from the forward end portion of the trigger-plate and throughwjhich the rod -16 loosely works. The block 11 in addition to carrying the hammers 14 also carries a hammer-cooking lever 20,` which has its rear end portion projecting within Y ythe block recess 12 and pivoted therein short of its end, as at 21, and provided at the rear ofsuch pivot with a cross-pin 2 2, which has its opposite ends working through registering slots 23 in the side walls `of therecess 12 and projecting into notches or incut portionsj24 in the respective hammers. When the hammers 14 are in fired or uncooked position and the, forward end of the lever 20 isY raised from its normal reclining position the ends of the lever-pin 22 are intenlded to coact with the lower end walls of the hammer recesses 24 and to move the hammers in unison to full cocked position against the tension of their firing-springs 15. The ham mer-cooking movements are automatically Iimparted to the lever 20 upon a relative breaking ofthe stock and barrels, as hereinafter described.

A sear 25is mounted at each side of the block 11 immediately to the rear of the base portion of its hammer 14,` being pivot-ally carried by a stud 26 projecting from'the associated side of said block. A spring 27 acts upon the forward end' ortion of the sear 25 to hold its nose in yiel ing engagement with a notch 28 in the hammer when the hammer is cocked, and has its tail-piece projecting rearwardly from its pivot and angling'inwardly at its free end over the inner end portion 29 of a trigger 30. These triggers are two in number, one being provided for each hammer, and each has its upper end portion of web form and working upwardly through a registering slot in the triggerplate 6 with its forward end projected within thel rear end recess 13 of the block 11 and pivoted therein on a pln 31, which ismounted at its ends in the walls ofsuch recess. The'triggers 29-30 are shown as being yieldingly retained in one position of their movements by a spring 32. This spring is secured at its forward end vwithin the. base ortion of the recess 13 and has arms projecting, rearwardly therefrom with their rear ends in engagement with the inner sidesof the web portions 29 of the respective triggers.

A safe-bar 33 is slidingly carried by a stud 34 rising from the trigger-plate .6, and has its forward 'end working between the web-portions 29 of the two triggers and slotted to slidingly work over the. pivot-pin 31. This safe-baris preferably provided on each side thereof with two studs 35 and '36 which,l .when the safe-bar is moved rearfwardly, `respectively move over the rear angled end of the associated sear 25 and a spur 37 on the upper rear end portion of the associated trigger web'29, thus locking both the sear and the trigger against hammer releasing movements. y

AWhen the trigger-plate and parts carried thereby are attached to the frame the safe'- bar 33 and triggers 3() are disposed under the frame arm 2 and the block 11 and hammers 14 it up within a registering recess 38 in the lower portion of the frame, such recess being provided at its sides with upward extensions 39 for the upper ends of the hammers" to work in. The forward arm ofthe hammer-cooking lever 20 works forwardly from the recess 38 intoA a. narrow longitudinally extending recess 40 in the center of the frame arm- 3, such recess opening through the top of .said armto permit parts carried by the gun barrels to work into or -out of the same upon a relative closing or opening ofthe stock and barrels, as shown Ain Figs. 3 and' 8.

The lbarrels 5 are provided atthe rear of their pivotal point of connection to the frame vwith a longitudinally-extending downwardly-projecting lug 41 in position to Vwork down within the recess 40 when the barrels are in' closed position. A finger v42 ypivotally hangs from`the lug 41 and has its lower endangled'fo'rwardly and hooked under the forward end of the lever 20, whereby the lever will be moved to effect a cooking of the hammers when the barrels are moved to open or shell ejecting position' as shown in Figs.. 1 and 3. Thev forward end of the lug 41 forms one member of the gun hinge and removably carries a ushvbar 43 the rear end of which is int rust contact with the forward sideof the @nger 42 to hold the same in llever engagingposif tion. The finger 42 lis yieldingly held in .contact with the push-bar 43 by a springpressed plunger 44, which is carried 1n the lower rear end' portion of the lug 41, as best shown in Fig. 1. Thepush-bar 43 is preferably of forked form to adapted it to Vstraddle the rear end portion 'of the lug'41',`

each side of the lug "being recessed .for the respective legs of the'push-bar'to'iwork in, as shown.

45 designates the customary barrel-locking lever which is pivoted `to the top of the frame 1 yfor lateral swinging movements relative thereto, and lhas its forward end provided with a nose-'piece 46,-whih, when the barrels are in closed position',l is in tended' to interlock with thennotched tongue 47 projecting rearwardly from between ,the rear ends of the barrels, 'such tongue fitting down within a 'registering recess 48 in the frame. The lever 45' is fiXedly carried by a stub-shaft 49, which is mounted for rotary movements in a circular vertically-disposed socket 50 in the top portion of the frame, which socket opens at its lower end into the socket 38. of the frame into which the trigger-plate block 11 projects.

Mounted in the upper portion of the recess 38v immediately below the lower end of ,the socket 50 for longitudinal reciprocatory movements relative to the frame is a lock-bar 51, which when the frame and barrels are in closed position, is intended to have its forward end project into a notch 52 in the rear end of the barrel lug 41, as shown in Fig. 8, thus preventing an opening of the gun until the bar 51 has been moved rearwardly for such purpose. f The reciprocatory movements of the bar 51 are imparted thereto Vfrom rotary movements of the lever 45 and attached stubshaft 49 through vthe mediumv of a block 53, which block is fixed to the bar 51 by a screw 54,.

and isshown in Fig. 5 as straddling the bar 51 withits legs in sliding tongue and groove connect-ion therewith, and as having a stud 55 projecting'upwardly from one side there-V of 1nto a reglstering recess 56 in the lower end of the stub-shaft 49 at one side of its axis. The stud 55 and socket 56 are so arranged that upon a swinging ofthe locking-lever 45 from locking position the bar 51 and attached block 53 will be moved rearwardly so as to move the nose of the bar from engagement with the notch 52 of the barrel flange, thus permitting an opening of the gun, and that upon a movement of the lever 45 to'closed or barrel-locking position the bar 51 will be moved forwardly to engage the notch 52. vThe screw 54, which connects the bar 51 and block 53, is pref erably projected through a longitudinallyextending slot in the bar 51 to permit of a relative adjustment of the bar and block as the assembling of the parts or a wearing `of the same may require.

In order to prevent a movement ofthe lever 45 and connected parts to barrel-locking position when the barrels are in open postion, or until they have been moved into closed position, I provide a spring-pressed locking plunger 57, which is mounted for vertical movements in a socket in the frame l immediately'above the forward end portion of the bar 51, and has its lower end yieldingly pressed against the top surface of the bar by a spring 58. The plunger 57 is providedat its lower end with a spur, which, when the bar 51 is in the retracted posit-ion shown in Fig. 3, fits into a registering socket 59 in the bar to lock the bar in such retracted position. The plunger 57 is moved to bar releasing position by, the rearward movement of a wedge-block 60 in coaction with an inclined surface or shoulder of such plunger, said wedge-block having a part projecting without the forward locking position.

lside of the frame in position t-o be engaged and pressed inwardly by the coaction therewith of the ejector-plate 61, or other registering part of the barrels, when the barrels are moved to closed position, such contact not taking place until the barrels are nearly .in closed position relative to the frame, as best shownv in Fig. 8. It is thus apparent that upon a closing of the barrels the ejector-plate 61, or other registering portion of the barrels, will coact with the outer end of the wedge-block 60 and force it inwardly to impart a bar releasing movement to the plunger 57 to permit a movement of the lever 54 and other barrel locking parts to The vvedge-block 6() is shown as being retained within the frame, by a screw-stud 62 coacting with a shoulder thereon. Y

In order that the safe-bar 33 may have automat-ic locking movements communicated thereto upon an opening of the gun, the rear end of the lock-bar 51 and the forward end of the safe-bar are terminated in substantially abuttingpositions whereby a rearward or barrelreleasing movement of the lock-bar will move the safe-bar to sear and trigger locking position. `When the gun has been closed the safe-bar may be moved forward to inoperative position by a forward-movement of a finger-slide 63 on the top surface of the frame, such slide having a tongue working downwardly through a slot in the frame arm 2 and forked to straddle the upturned rear end of the 'safe-bar, as shown.- A spring-finger 64 acts upon a pin 65 on the finger-slide tongue to yieldingly retain the slide at the limit of either direction of its movements, as will be apparent.'

The screw 8, which assists in attaching the, trigger-plate and associated parts to the frame, is shown as projecting through a slot 8, in the lock-bar 51 and has its head preferably countersunk relative to the trigger-plate 6, as shown in Figs. 3 and 8, and a screw 66, which secures the forward end of the trigger-guard 67 to the plate 6, is shown as being threaded into suchy countersink.

68, 68 designate the firing'pins which are mounted for reciprocatory movements 1n the frame 1 in position to be struck by the respective hammers 14.

In the coupling together of the frame and barrels of a gun it is customary to hook the forward end of the barrel lug 41 around the rear portion of the pivot-pin 70, which is mounted in the forward end portion of the frame arm 3, the barrel-lug being retained in hooked engagement therewith by the attaching of the forearm 4 of the frame to the barrels, as is well understood in the art. In order to compensate for wear which may occur between the coacting sul" faces of the barrel lug 41 and the pin 70, I encircle the pivot-pin with an eccentric bushing 7'1 upon the pin will effect an ad` justinent of the barrels relative to the gun frame so as to take up any wear or looseness between the same. In Fig. 1 the bush` ing 71 is shown as being clamped in adjusted positionv relative to thepin by av block7 2, which is firmly drawn to the outer side of the bushing by a screw 73 that projects through an opening in said block and a registering circular slot 74 in the bushing and threads transverselyinto the pivot pin 70, thus effecting a clamping or binding of the bushing between the pin and block. The block 72 in addition to cooperating with the screw 73 to clamp the bushing 71 in adjusted position, has its upper end projected into'position to coact with the forward-end of the ejector-plate rod 75 to impart shell ejecting movements thereto when the barrel is moved to open position, as shown. In Fig. 3 the bushing member 71 is shown as being located in adjusted position by the project-ion of the clamping-screw 73 through a clamping-block 76 and interposed washer member 77, t-he forward sides of which block and washer are shown in detail-in Figs and 7. In adjusting the bushing 71 to effect a tightening of the frame andbarrel, it is intended to be turned to vthe left, or in the direction indicated by the arrow in Fig. 3, and when so adjusted effects both a lowering ofthe barrels upon the frame extension 3 anda rearward move` ment thereof toward the breech portion of the frame. l To effect such adjustment of t-he bushing, the-barrels are first removed from the frame and a pointed tool engaged at its end with the small opening 78 in the forward side of the bushing and pushed downwardly to impart the desired adjustingv movement thereto, Iit being understood that the screw 73 is first loosened for such purpose. The clamping-block 76 is made in t-he shape shown so that, in addition to serving as a clamping block for the adjustablebushing it is adapted to perform other func-.

tions which form no part of the present invention and therefore need notY be described.

In theuse/of my improved gun, the operator, to open the barrels relative to the frame, throws the locking lever 5to the right to move the locking nose thereof from engagement with the notched tongue 4:7 at the rear end ofthe barrels, as with the guns of this nature commonly used; The moving of the lever 45 in this manner, in. addition to [releasing its engagement with the barrels,

also effects a rearward movement of the lockbar 51 from locking engagement with the notch 52 in the barrel lug .due to the coare held by the respective sears 25.

operative action of the pin and socket 55 and 56 on the lever-shaft and the block 53 attached to the lock-bar. When the lock-bar 51rhas reached the limit of its rearward movement., the spring-influenced plunger 57 drops into locking engagement with a registering socket 59 therein to hold the barrelloycking parts in released position until the barrels have been again moved to their `closed position. Upon 'a movement of the barrels to closed position the ejector-plate 61, in the present instance, coacts with the projected end of the wedge block 60 to throw such block inward in coaction with the plunger 57 to raise such plunger from bar-locking position, thus permitting a return of the locking parts to barrel locking 'positions Upon an opening movement of the barrels t-he finger/ L12, which is carried by the barrel lug 41, moves the hammer cooking lever 20 to cause the ends of the pin 22 thereof to engage the lower end wall of the hammer recesses 24 vand move such hammers to full lcocked positions against the tension of the hammer springs 15, in which positions they The safe-bar 33, which was automatically moved rearwardly to place the pins 35 and 36 thereof in locking engagement with the respective rear angledends of the sears 25 and the trigger-spurs 37, pre-vents a release of the sears from the hammers until the safe f,

bar has been moved to inoperative-position for such purpose. The coaction of the safebar with both` the triggers and the sears not only prevents a firing movement of the triggers but also prevents the sears 6 from jarring from engagement with the hammer notches 28 as might be the case if the triggers only were locked against sear releasing movements. Upon a closing of the gun barrels relative. to the frame, the operator can move the finger slided 63 at will to move the safe-bar from locking position, or vice versa. To remove the trigger `plate 6 and attached parts from the frame for the purpose of cleaning, repairing or the like, it is only.

necessary to remove the screws 8, 9 and 66, the screw 66 being removed to render access to the screw 8. When the lock mechanism has thus been removed from the frame, it is a very simple matter to remove the separate lock parts therefrom, the hammers being loosely mounted on their pivot pins and held thereon by the side walls of the frame, as is also the cas'e with the sears 25. The trigger-pin 31 and safe-bar holding pin in the stud 34 are also capable of being easily removed to permit a quick removal of the triggers and safe-bar.

It is apparent from the above that I have not only provided a gun which is simple, strong and durable in its ccnstructure but is economical of manufacture and is free from a considerable number of the complicated lock Ymechanism parts commonly employed in guns of this character.

I wish it understood that my invention is not limited to any specific construction or arrangement of the parts except in so far as such limitations are specified in the claims.
